棉花小麦套种技术规程

规范麦棉套种种植，解决粮棉争地矛盾，稳定棉花生产，实现粮食和棉花的优质高产高效。总结多年棉花小麦套种栽培的经验，筛选已发表的研究结果进行组装优化并进行田间验证。根据麦棉套种高产栽培技术规范化要求，从品种选择、播种技术、水肥管理、整枝打顶、化学调控、病虫害防治等方面阐述了麦棉套种技术。有效解决中国棉麦套种生产中存在的共生期争水、争肥、遮荫蔽光矛盾，充分利用时间、空间、光能和土地资源，使两熟棉花吐絮早而集中，有利于提高中国粮棉产量和小麦、纤维品质，实现粮棉同步增长。规程的制定便于农民进行田间管理操作，是当前解决粮棉争地矛盾，稳定棉花生产，争取麦棉双丰收，增加棉农经济收入的重要途径。

Technical Protocol of Cotton-wheat Relay Intercropping

The aims were to normalize the wheat-cotton relay intercropping planting, solve the contradiction of contending soil between food stuff and cotton, stabilize cotton production and achieve good quality and high yield as well as efficiency of grain and cotton. By summarizing years of experiences of the wheat-cotton relay intercropping cultivation, and screening published research results, the cultivation techniques were combined, optimized and verified through field tests. Based on the technology standardization requirements, wheat-cotton relay intercropping cultivating techniques were elaborated in varieties selection, sowing techniques, waterfertilizer management, plant pruning and topping, chemical control, disease as well as pest control etc, to solve the conflict of contending for water, fertilizer, shading light during symbiotic period. The double cropping cotton could open bolls early and intensively by making full use of time, space, light energy and land resources, which was beneficial to improve the quality and production of grain and cotton, and to achieve synchronized growth of grain and cotton. The regulation was made to provide convenience for farmers with field management operation, which was an effective way to solve the contradiction of contending soil between food stuff and cotton, to stabilize the cotton production, to achieve the double harvest of wheat and enhance the economic income of farmers.
